PART II: PROFILE DATA 



6. The beach profile data were collected from a shore-parallel baseline 

 landward of the dune out to a depth of between -8 to -9 m, which extended up 

 to 1,000 m seaward of the baseline on the longer profiles. All profiles were 

 referenced to the 1929 National Geodetic Vertical Datum (NGVD) . Collection 

 was approximately biweekly, but varied between each individual profile. Some 

 profiles closely bracketed storm events. 



7. All profiles were surveyed using the FRF Coastal Research Amphibious 

 Buggy (CRAB) for the subaqueous portion of the profile. (See Birkemeier and 

 Mason (1984) for details on the CRAB.) The dry beach and dune portions of the 

 profile were surveyed by standard rod method, placing the rod at regular 

 intervals or breaks in slope along the profile between the regular intervals 

 (Howd and Birkemeier 1987). A Zeiss Elta-2 electronic surveying instrument 

 was used to collect the profile data. 



8. Pertinent data on the profiles used in this report are given in 

 Table 1. The time scale of these data allows resolution from a few days to 

 17.8 months. Howd and Birkemeier (1987) described five profile configurations 

 found at the FRF ranging from a minimal to a triple bar. Four of these pro- 

 file types were observed during the study ranging from (a) the minimal bar 

 feature, with a concave profile shape; (b) single inner bar centering around 

 200 m seaward of the baseline; (c) double bar with a prominent inner bar and a 

 lower relief outer bar centering around 350 m from the baseline; and (d) tri- 

 ple bar with two bars in the inner region between 100 and 200 m, and the outer 

 bar around 350 m. Figure 3 shows an example profile from each of the four 

 categories. The most common profile type during the study period was the 

 single inner bar. The profile data were analyzed and plotted using the Inter- 

 active Survey Reduction Program (ISRP) as described in Birkemeier (1984).
